I've never bothered with much beyond candlestick, so this is fascinating stuff! Can you clarify the method for calculating the estimated drop when support is pierced?

"To do this calculation, you count the number of columns at the widest point when it fell (horizontal green line) and there is 5 of them. Multiply it by the amount of boxes to a reversal (3 in this case) So 3x5 = 15."

The columns across is simple enough, but I'm confused as to how you got the multiplicand of 3.
